3118	Here is a matrix of mmap possibilities:
3119	mmap private not fixed
3120	mmap private fixed at somewhere currently unmapped
3121	mmap private fixed at somewhere already mapped
3122	mmap shared not fixed
3123	mmap shared fixed at somewhere currently unmapped
3124	mmap shared fixed at somewhere already mapped
3125	For private mappings, we should verify that changes cannot be read()
3126	back from the file, nor mmap's back from the file at a different
3127	address. (There have been systems where private was not correctly
3128	implemented like the infamous i386 svr4.0, and systems where the
3129	VM page cache was not coherent with the filesystem buffer cache
3130	like early versions of FreeBSD and possibly contemporary NetBSD.)
3131	For shared mappings, we should conversely verify that changes get
3132	propogated back to all the places they're supposed to be.
3133
3134	Grep wants private fixed already mapped.
3135	The main things grep needs to know about mmap are:
3136	* does it exist and is it safe to write into the mmap'd area
3137	* how to use it (BSD variants) */
